Abstract
The experimental population in Żerniki Farm of IZ consisted of 72 weaner piglets, crossbreeds between breeds PLW and PL, which were chosen by random and divided into 2 groups of equal number of 36 heads, in each group, with a division into gilts and hogs. Fattening began at 25 kg body weight and stopped having achieved 100 kg body weight. Basic nutrient of complete mixtures for both feeding groups was wheat, triticale and barley. The main carrier of protein in control feed were soybean extracted meal. The source of protein in complete mixture of nutritive fodder in experimental group was pea meal, potato protein and fish meal which replaced the share of soybean extracted meal in control group. The aim of conducted studies was defining the impact of using in porker nutrition two kinds of complete mixtures on the growth rate of the animals during fattening, on chosen slaughter and backfat characteristics. Fatteners from the experimental group were characterized by slightly higher daily gains (of 3,2%) compared with the control group, however, were not statistically confirmed. Slaughter yield of fatteners from the control group was slightly higher compared to the experimental group. The carcass leanness of fatteners from the experimental group was lesser compared with control group (P ≤ 0,05).
